A pin (21) is provided for engagement in a hole (15) in a sliding hatch, and is movable forwards and backwards for opening and closing the sliding hatch. The pin is supported by a component (20), which is movably controlled on a slide (17,) which itself is movable in the forward and backward directions. This allows movement, in relation to the slide, in two mutually orthogonal directions. The component, through the slide movement, comes against a stationary stop (24) in a terminating part of the slide movement in one direction. The component is lifted from the cassette (12) with the sliding hatch turned towards the slide. By locating against the stop, it lowers towards the cassette during an initial part of the slide movement in the other direction. The pin, through movement towards and away from the cassette, is brought in and out of engagement with the hole in the sliding hatch. The component comprises a block (20) which is controlled for movement relative to the slide, between its arms. |
